This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X75N, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

The AirTAC SU32~50 Standard Cylinder SU32X75N is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X75N, which matches its bore, stroke, force and mounting.
The AirTAC SU32X75N is a discontinued double-acting profile-type cylinder with a 32mm bore and 75mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8" port. AirTAC replaced this end-of-life unit with the SAU32X75N, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU replacement adds modern CMSG/DMSG/EMSG switch support on its -S variants, plus a new SAUF built-in-valve option. The NBR seal handles -20 to +70C.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X75N carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X75N produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×75 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Uses the 402N push force at 0.5MPa to reliably knock lightweight molded parts out of a fixture during short 75mm travel.
Actuates a routing gate on a packaging line, where the compact 32mm profile body saves space without needing ISO 15552 clearance.
To replace this SU32X75N, order the SAU32X75N. Confirm the 1/8" port, M10x1.25 rod thread, PT thread type, and SC-series mounts (LB/FA/FB/CA/CB). Since this is a no-S SKU, it cannot take a sensor; if you need position detection, switch to an SAU32X75NS and use CMSG/DMSG/EMSG switches. For sizing both ways: dropping to a smaller bore loses thrust, while stepping up to a 40mm bore yields 628N push at 0.5MPa. The 75mm stroke is standard. Note that a plain cylinder drifts without live air; the cushions only decelerate. For load holding on air loss, add an external rod lock or pilot-operated check valve. The SAUF valve-integrated variant can simplify cycling if you lack a separate solenoid.
Replacement checklist
Yes, the SU32X75N is discontinued. The direct replacement is the SAU32X75N. It shares the same 32mm bore, 75mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it fits the same application.
It provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N at 0.9MPa, and an 82kgf max at 1.0MPa. Because this specific SKU lacks a magnet (-S), it cannot accept a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches on its -S variants.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X75N replacement — usually within 7-8 hours.
